Course Descriptions

ENR 157 - Digital Systems

4 Credits

This course introduces the basic logic functions, components and methodologies used in the design of digital systems. Digital electronic topics will include the basic logic gates, Boolean algebra, number systems, digital arithmetic, combinational logic circuits, multiplexers, decoders and flip-flops and registers. Digital system applications will include counters, magnitude comparators, Analog-to-Digital and Digital-to-Analog conversions, feedback control, sensor interfacing and signal conditioning. Students will use schematic capture and VHDL programming to implement the digital systems on a Field Programmable Gate Array (FPGA) development board. Various add-on power supply and sensor boards will also be utilized in the laboratory component of the course. The course will culminate in a team design-build project requiring prototype demonstration, written documentation and presentation.

Prerequisite: MTH 165 or higher.
